先看下面这个,要看完了,,,http://bbs.mjtd.com/forum.php?mod=viewthread&tid=21383再看我给你改的程序。。。注意,你的程序,最后command部分是错误的,所以程序无法完成,这部分我未改,注意subtract命令的用法。。。- (defun jiansuo (ct / f1 p)
- (setq f1 (open "e:\\abc.txt" "r"))
- (repeat ct
- (setq p (read (read-line f1)))
- )
- (close f1)
- p
- )
- (defun c:luos1 (/ lst item l d ct p p1 ent_p ent_c)
- (setq lst '((10 20 200) (12 25 260) (14 25 260) (16 30 300) (18 35 300)

- (72 180 380) (80 200 380)(90 220 500) (100 220 500)))
- (while (not (assoc (setq d (getreal "\n请输入螺栓的直径:")) lst)))
- (setq item (assoc d lst))
- (setq l (getreal (strcat "\n请输入螺栓的长度在" (rtos (cadr item)) "到" (rtos (last item)) "之间:")))
- (if (and (> l (- (cadr item) 0.01)) (< l (- (caddr item) 0.01)))
- (progn
- (setq ct (1+ (- (length lst) (length (member item lst)))))
- (setq lst (jiansuo ct))

- ((or (> l 125) (< l 200.01)) (setq l0 (+ (* d 2) 12)))
